BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Grace’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Pennant Hills, New South Wales, Australia. The objective of the breeding program is to create new shrub-type Mandevilla plants with strong stems and numerous attractive flowers.

The new Mandevilla plant originated from a cross-pollination made by the Inventor in Pennant Hills, New South Wales, Australia in December, 2003 of a proprietary selection of Mandevilla hybrida identified as code number X02.5, not patented, as the female, or seed parent with Mandevilla hybrida ‘Sunmandecrim’, disclosed in U.S. Plant Pat. No. 15,539, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Macquarie Fields, New South Wales, Australia in November, 2005.

Asexual reproduction of the new Mandevilla plant by cuttings in Macquarie Fields, New South Wales, Australia, since December, 2005, has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Grace’. These characteristics in combination distinguish ‘Grace’ as a new and distinct Mandevilla plant:

-   -   1. Compact, upright and mounding plant habit.     -   2. Strong stems.     -   3. Early and freely flowering habit.     -   4. Large greyed purple-colored flowers.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla have smaller flowers than plants         of the female parent selection.     -   2. Plants of the new Mandevilla and the female parent selection         differ slightly in flower color.

Plants of the new Mandevilla can be compared to plants of the male parent, ‘Sunmandecrim’. Plants of the new Mandevilla differ from plants of ‘Sunmandecrim’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more compact than plants of         ‘Sunmandecrim’.     -   2. Plants of the new Mandevilla and ‘Sunmandecrim’ differ in         flower color as plants of ‘Sunmandecrim’ have crimson         red-colored flowers.

Plants of the new Mandevilla can be compared to plants of Mandevilla hybrida ‘Gina’, disclosed in a U.S. Plant patent application Ser. No. 13/385,067. Plants of the new Mandevilla differ primarily from plants of ‘Gina’ in flower color as plants of ‘Gina’ have red-colored flowers.

Plants of the new Mandevilla can be compared to plants of Mandevilla hybrida ‘Rita’, disclosed in a U.S. Plant patent application Ser. No. 13/385,075. Plants of the new Mandevilla differ primarily from plants of ‘Rita’ in flower color as plants of ‘Rita’ have dark red purple-colored flowers.

Plants of the new Mandevilla can also be compared to plants of Mandevilla hybrida ‘Sunparabeni’, disclosed in U.S. Plant Pat. No. 19,672. Plants of the new Mandevilla differ primarily from plants of ‘Sunparabeni’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are shorter than plants of         ‘Sunparabeni’.     -   2. Plants of the new Mandevilla flower earlier than plants of         ‘Sunparabeni’.     -   3. Flowers of plants of the new Mandevilla are lighter red in         color than flowers of plants of ‘Sunparabeni’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and summer with three plants in 20-cm containers in a polyethylene-covered greenhouse in Bonsall, Calif. under commercial production cultural practices. During the production of the plants, day temperatures ranged from 18° C. to 32° C., night temperatures ranged from 7° C. to 18° C. and light levels ranged from 7,000 to 8,000 foot-candles. Plants were pinched one time and were two months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
